I have been researching and using essential oils (EO) for some time with wonderful results! I have bought several diffusers for my home and my husband's office and we have avoided our yearly upper respiratory problems. I will share information on that soon. A new topic I'm discovering is Raynaud's syndrome and how Black Pepper EO can help!
Black pepper with carrier oil can also be rubbed on feet and hands before going out in the cold...skiing, working, shoveling snow, etc.
